Toall whom it may concern:

fBe it known that I, -VIcToR J. EMERY,y a citizen of the United States, residing at -Quincy,in the county ofNorfolk and State of Massachusetts, have invented certain new and useful Improvements in Means for Distributin Water to Water-Jackets of Multiple-Cy inder Engines; and I do hereby declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in theart to which it-ajlpertains to make and use the same.

T e invention relates to means for securing an equal iow of water from a single pump or circulating device to the separate water jackets'of multiple cylinder hydrocarbon or gas engines.

vIn supplyin water to the different water jackets of m tiple cylinder engines from a common pump or other circulating device, diliculty has been encountered in securing an equal How of water to the different jackets under the varying conditions of use. It has een common practice in an endeavor to secure equal distribution to introduce controlling valves in the pipes leading to the ackets and to maintain a comparatively igh pressure in the supply pipe, a release or waste valve being provided to allow the escape ofany surplus in the supply pipe. It has been found however that it is necessary to continually vary the adjustment of the regulating valves in order to approximate an equal distribution of the waterA and that if condition, a change of conditions due to stopping or starting the-engine for instance may and usually does require a readjustment of the -count of its unreliability as well as on account of the power required to maintain the pressure in the supply pipe and also on account of the size of pump required.

It is the obj ect of the present invention to provide an apparatus by which an equal distribution of water to the water jackets is insured under the varying conditions which may obtain during the running of the engine without change of adjustment and without the necessity of forcing the water through the pipes under heavy pressure. -ThisI accomplish by inserting between the pump and water jackets a distributing device which subdivides the water entering its inlet opentities low to the outlet openings 'ing and directs substantially equal parts thereof tothe different outlet openings .which communicate through separate piping with different water jackets.

The distributing device consists of a casing provided with an inlet adapted to connect with a pipe leading from the water supplying device, and two (or more) outlets, the 'combined areas of which are ,substantially equal to the area of the inlet and are separated by. a partition (or by partitions) arranged Y's-ubstantially in line with the inlet and subdividing the inlet area into substantially equal parts. The water entering the inlet opening strikes against the end of the partition (or partitions) and is divided so that equal quanand thence through the pipes to the water jackets.

The invention will be understood from the above and from the following detailed-Adescription of the apparatus shown in the taccompanying drawings.

In these drawings Figure 1 is an elevation showing a multiple cylinder hydrocarbonlengine provided with the invention; Fig. -2 isa horizontal sectional view through the distributing device; Fig. 3 is an end viewvlooking towards the left in Fig. 2,' Fig-4 isa side elevation partly in section, and Fig. -5 isi-a horizontal sectional view of ra distributer adapted for use in connection with an'engine having three separate water jackets.

As indicated in Fig. 1 the engine is pro.- vided with a plurality of cylinders inclosedrifn the separate water jackets a, b. Thewater for the jacket a is supplied throu hvaipe c and discharged through a pipe 'whie the water for the jacket b is supplied through-'a pipe e and discharged through apipe'f. rThe water is circulated or forced through the water jackets by the action of a (puni g driven from the engine and provide wit a suction pipe 7L and a delivery or supply pipe '11. The water for both-water `ackets is sulpplied by the pump g and is 'de ivered bylt e supply pipe t to a distributerby which the water forced through the pipe is subdivided and equal quantities directed into pipes c and e.

The distributer comprises a 'casing jhaving an inlet opening-7c at one end and two outlet openings Z at the o posite end. 'The interior of the casing is subdivided bya partition o which extends from the exit end'towards the inlet end in line with the inlet openthe inlet opening area in halves.

ing c, the front end of the partition dividing The outlet openings each have substantially one half the area of the inlet opening and are .preferably arranged symmetrically with relation to the axis of the inlet opening and as nearly in line with the inlet opening as is practicable. The cross sectional shape of the passages on opposite sides of the partition o referably c anges gradually from semicircu ar to circular so that the passage area is substantially constant from the inlet to the outlets. The inlet opening 7c is threaded to receive the end of the pipe 'L andthe outlet openings Z are threaded to receive the ends of pipes c and e. The water entering through the pipe 'i strikes the end of the partition o and is subdivided, equal volumes flowing on o posite sides of the partition and being de ivered through the pipes c and e to the water jackets,

In Fig. 5 a distributing device is shown adapted to subdivide the water entering the inlet opening into three substantially equal parts and to deliver equal quantities of water to three different water jackets. As here shown the casing y" of the distributing device is provided with a single inlet 1c at one end and with three outlet o enings l. Each opening Zhas substantiallyone third the area ofthe inlet opening 7c and the adjacent outlet openings arese arated by partitions o which extend from tlie outlet end towards the inlet end in line with the inlet and are ar" ranged to subdivide the inlet area into three equal arts. In this case the water entering thein et strikes against the ends of the artitions and is subdivided equal volumes owingto the three outlet o enings and thence to the diierent water jac (ets. In each case there is a single inlet opening at one end of l the distributer casing and a plurality-of outlet openings in the opposite end of thecasing and adjacent outlet openings are separated by a partition extending from the outlet end towards and in line with the inlet end so that the inlet area is subdivided into equal areas corresponding in number to the number of outlet openings, and in each case the water entering the inlet o ening is subdivided so that equal volumes ow to the different outlets and thence to the different water ackets.

What I claim is 1. A multiple cylinder engine having in combination a plurality of water jackets, a common water circulating device for supplying water thereto, a distributing device provided at one end with an inlet communicating with the circulating device, and at the opposite end with a plurality of outlets cornmunicating with the respective water jackets, and with a partition between the adjacent outlets extending from the outlet end towards and in line with the inlet and so arranged thatthe inlet area is subdivided thereby into equal areas corresponding in number to the number of outlet openings, substantially as described.

2. A multiple cylinder engine having in combination a plurality of water jackets, a common water circulating device for supplying water thereto, a distributing device provided at one end with an inlet communicating with the circulating device and at the opposite end with a plurality of outlets the combined area of which is substantially equal to the area of the inlet, a partition between adjacent outlets extending'l from the outlet end towards and inline with the inlet and arranged to subdivide the inlet area into areas eachof which is substantially equal to the corresponding outlet area, substantially as described.

3. A device for distributin water to the water jackets of multiple cy inder engines com r1s1n a casino' havin an inlet o ening at one end, a-plurality of outlet openings in the opposite end, a partition between adjacent outlet openings extending from the outlet end towards and in line with the inlet opening and arranged to subdivide the inlet area into areas corresponding in size and number to the outlet openings, substantially as described.

4. A device for Idist'ributin water to the water jackets of multiple cy inder engines comprising a casing having an inlet opening at one end, a plurality of similar outlet openings at the opposite end, the combined area of which is substantially equal to the area of the inlet, a partition between adjacent outlet openings extending from the outlet end towards and in line with the inlet opening and dividing the inlet area into substantially equal areas corres onding in number to the number of the out et openings, substantially as described.

5. A device for distributing water to the water` jackets of multiple cylinder engines comprising a casing, a circular inlet opening at one end, a plurality of circular outlet openings at the opposite end the combined areas of the inlet opening, a partition between adjacent outlet openings extending from the outlet end towards and in line with the inlet opening and arranged to divide the inlet area into substantially equal areas corresponding to the number of outlet openings and to subdivide the interior of the casing into passages the cross sectional areas of which are substantially constant from end to end, substantially as described.

In testimony whereof I aflix my signature, in presence of two witnesses.
